13: The Sins of the Father

Head southeast with your squad towards the yellow objective marker. Capt. Price directs you to jump onto a dumpster.

On the dumpster, zoom in on the troops in the watch tower. When Price gives the signal, take them out. Since the watchtower has been taken care of, head down to where the rest of your squad is fighting and provide sniper cover.

Shoot the guys in the tower and then help clear out the remaining enemies.

After the enemies are destroyed, assemble in the parking lot of the gas station.

Intelligence: During the initial attack after you snipe the tower guards make your way into the diner. Once inside on a table to the east-northeast is the intel.

The screen will turn black -- indicating a time lapse -- and then fade back in. You're in the watch tower, while your squad on the ground. Plus, everyone will wear enemy uniforms, as they plan an ambush.

Once your squad starts shooting, do the same. You will make quick work of the enemies, but then get blown out of the tower, allowing the target, Zahkhaev, will get away.

Shoot the enemies and then wait for the tower to get knocked over.

After you get up from the destroyed tower, you will be given a new objective: track down the fleeing terrorist, Zahkhaev. Start sprinting northwest through the junkyard.

Shoot the dog that tries to ambush you.

Continue northwest until you come out to a road, then turn and head north by northeast, into the city.

When you reach the edge of the town, head left into the houses. From the houses, shoot the troops that are in the street. Watch out for Zakhaev, though -- if you kill him the mission is over.

Use the buildings for cover, but do not shoot Zakhaev.

Your progression into the town will prompt Zakhaev to run. Follow him northwest into an alleyway.

The alleyway will end with a sheet metal fence. Beyond the fence will be several hostiles hiding amongst the cars and some on the roofs. Stay behind the sheet metal and take them out.

Shoot the enemies in front of you until you are warned of enemies on your flank.

Listen carefully to the orders given by the helicopter operator; he will tell you where the enemies are before you even get there.

Intelligence: Once you've eliminated most of the resitance there is a building to the right of where the enemy was walking between the cars. On that building are some stairs, go up the stairs and be sure to check for enemies before just running in. Once inside that second floor there is the intel laptop.

You will eventually make it out of the alley and back onto the street. Zakhaev will run into a large apartment building. Do not pursue him but instead take cover. Wait behind cover until a friendly helicopter comes in and takes out the machine gun on the building's fifth floor.

Enter the building and then start fighting your way up. Each floor will have several enemies, so be careful.

Eventually, you'll run into another fortified enemy position; do not fight the position, just let your air support take it out.

Continue to follow the objective marker through the wreckage of the building. It will lead you up onto the roof of the building.

Once on the roof you will be ordered to restrain the cornered Zakhaev. Unfortunately, he will kill himself before you have the chance to do so. Mission complete.
